Ive had to change powders since I cant find 322 anywhereI have a rebarreled mini-Mauser in 6PPC USA that I shoot the 70gr Nosler Ballistic tips in. I shoot 26.5 grs of H-322 with a CCI-400 primer loaded in Nosler 6PPC brass. It is deadly accurate with that load and have taken many, many deer with that load. Most have dropped in there tracks.
